Sept. 15, 1931. .1. G. HALL ETAL CLINKER TONGS Filed April l1, 1930 JOHN6. V4/ L Patented Sept. 15, 1931 PATENT FFICE JOHN Gr. HALL AND CARL It.HALL, OF CHICAGO, ILLINOIS CLINKER TONGS Application led April 11,

rlhis invention relates to improvements in clinker tongs, and has forone of its principal objects the provision of a tongs or similar devicefor removing clinkers and like objects from furnaces, stoves or otherheating plants.

One of the important objects of this invention is to provide in aclinker tongs, means for readily grasping and removing clinkers andother hot objects from a furnace or the like without danger or injury tothe hands of the operator, while at the same time providing a positiveacting device, and one which will securely grasp the clinker, so therewill be no danger of droppingit back into the fire box or upon the feetor other portions of the anatomy of the operator.

Another and still further important object of the invention is toprovide in a clinker tongs a. pair of unitary resilient arms which arenormally impelled toward each other by the inherent spring action of thetongs themselves and which arms have at their ends coacting clinkergrasping elements which are offset with relation to each other in two ormore planes, whereby a positive action will result.

Other and further important objects of the invention will be apparentfrom the disclosures in the accompanying drawings and followingspecification.

The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described.

in. the drawings:

Figure l is a side elevation of the improved clinker tongs of thisinvention.

Figure 2 is an end view of the same, illustra-ting particularly theoffset relationship of the clinker grasping arms.

Figure 3 is a detail view of one of the arm ends, illustrating a slightmodification.

Figure 4 is a side view of the arm end shown in Figure 3.

Figure 5 is a perspective view illustrating a modified form of clampingelement.

As shown in the drawings:

The reference numerals 10 and 12 indicate respectively the'arms of theimproved clinker tongs of this invention, the arms being formed of aunitary bar of resilient metal 1930. Serial No. 443,474.

having a spring loop 14 at their doubledover ends, this spring loopacting to bring the grasping ends 16 and 18 respectively of the armstogether in clinker-holding relationship whenin normal position.

From an inspection of Figure 1 of the drawings, it will be noted thatthe arms 10 and 12 are, crossed adjacent the points where they arelfashioned into the grasping ends and that these grasping endsthemselves have a series of integral humps or bends therein whichoverlap slightly at two or more points when viewed in a horizontalplane.

On the other hand, when the arms are viewed in a vertical plane, itwillbe seen that the grasping end 16 of the arm 10 is curved outwardly fromthe corresponding portion y of the grasping end 18 of the arm 12,thereby providing a space between these arms, which space is irregularlyshaped and accordingly, adapted to fit itself to more or less degreewith respect to the contour of an ordinary clinker or the like.

In Figures 3 and 4 is illustrated a slight modification of the inventionwhereby each one of the grasping ends of the arms is fashioned withintegral curves or bends as shown at 20, and furthermore, the same isfashioned to provide an additional grasping surface, portions of thisfashioned element being punched out and bent inwardly as shown at 22 toprovide points which penetrate more or less into the bodyof the clinkeror other element which is to be withdrawn from the fire or handled insome other way by the tongs.

As shown in Figure 5, a still further modification of one of thegrasping arms is provided, the same being formed in a quite broad orflat member 24 which has integral lbends or curves `therein and whichalso has portions thereof cut away and bent inwardly as at 26 to formclinker grasping and supporting lugs. Y Y

It will be evident that herein is provided a clinker tongs or similarelement which will positively grasp and securely retain a clinker orother object, particularly when it is desired to withdraw the same froma hot fire or the like. The constriction and operation of the device isquite simple, and there-is nothing to get out of order or cause diioultyin operation. The spring action of the handle construction insures apositive gripping contact With the clinker itself, and in this Way,accidental dropping and subsequent damage is avoided.

7e are aware thatmany changes may be.

made and. numerous' details of construction varied throughout a Widerange Without departing from the principles of this invention, and We,therefore, do not purpose Vlimiting the patent granted hereon otherwisethan as necessitated by the prior art.

We claim as our invention.:

A clinker tongs, including in combination, a pair of joined integralarms, a resilient loop formed at the' juncture of the arms and elinkergrasping` ends Vat the outer portions of the' arms, said'clinkergrasping ends comprising lntegral extensions ofthe arms being provided.With integral bends and humps, and 1n- Wardly turned clinker supportingelementsY onthe. ends, said elements comprising integral. lugs,Apartially cutv away rom'the bodyv Y ofthe armv end..

In testimony whereof We aiix our signatures;

JOHN G. HALL. CARL R. HALL.
